Abstract

The invention relates to a data compression method of the type applied to a system for transmitting data by protocol data units (41i) between at least one sending terminal and at least one receiving terminal, each protocol data unit (41i) comprising a header field (42i) and a data field (43i), associating with a first sequence of N source protocol data units (41A, 41B, 41C), a second sequence of M protocol data units to be transmitted (51D, 51E), M being less than or equal to N, the data fields (53i) of the said protocol data units to be transmitted (51i) comprising, on the one hand, data (46i) corresponding to the compression, according to at least compression algorithm, of the data contained in the data fields (43i) of the said source protocol data units (41i), and, on the other hand, data (47i) enabling the said first sequence of source protocol data units (41i) to be reconstructed. <IMAGE>
